` Application led May 31, 1916. Serial No. 100,856.

To all whom t may concern.'

Be it known that I, SETE BORTREE, a citizen of the United States, residing at Ariel, in the county of Wayne and State of Pennsylvania, have invented new and useful Improvements in Horseshoe-Callis, of which the following is a specication.

This invention aims to provide a horseshoe call; constructed to permit of its attachment to or its removal from the shoe when desired, without necessitating the removal of the shoe from the hoof of the animal.

The .nature and advantages of the invention will be better understood from the following description when taken in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed.

Inthe drawing forming part of this speciication like numerals of reference indicate similar parts in the several views and where- 1n Figure 1 is a perspective view of a horseshoe showing the calks associated therewith.

Fig. 2 is a cross sectional view through the toe call; and showing one of the studs in position.

Fig. 3 is a lengthwise-sectional view through one of the heel calks and shoe.

Fig. 4 is a detail view of one of the heel calks.

Fig. 5 is a detail view of one calks.

Fig. 6 is a sectional view of the preferred form of the calk.

Referring more particularly to the drawing, 10 indicates generallyy the horseshoe which is of usual construction except that the same is provided adjacent the toe end with a pair of spaced openings 11, while the heel extremities of the shoe are provided with similar openings 12.

In accordance with my invention the toe calk illustrated in Fig. 5 comprises a body portion 13 which may be of any suitable design or cross-sectional configuration and has projecting therefrom spaced studs 14, which preferably form an integral part of the calli and are adapted to be received within the openings 11 in the shoe. The openings 11 and studs 14 are of such relative dimensions that when the studs are driven within rthe openings the calk is electively held associated with the shoe. The side of the body of the toe latter can be positioned within the groove between the body portion of the calk and the shoe for the purpose of slightly raising the calli, thereby loosening the same to permit of its removal from the shoe, without necessitating the removal of the shoe from the hooi:l of the animal. The construction of the calk also permits the latter to be associated with the shoe while the latter is in position upon the hoof of the animal.

The heel calk disclosed in Fig. 4 also comprises a Ybody portion 16 from which projects a stud 17, which studs are adapted .to be received within the openings 12 in the heel portions of the shoe. It is to be borne in mind that the studs V17 can also be smooth and of proper dimensions with respect to the openings 12 so asv to permit of the studs being driven within the openings in the manner described in connection with the toe calk. In this instance however the studs 17 are preferably threaded, as are also the openings 12, which permits of the heel calks being screwed within the openings 12, and thereby effectively maintained in position upon the shoe. The body portions 16 are preferably of angular formation in cross-section to accommodate a wrench to facilitate their application or removal from the shoe as the occasion may demand, while the heel portions of the shoe are each provided with a transverse groove or recess 18 which receives the body portion of the calk when the latter is associated with the shoe, the opposedwalls of the recess engaging the adjacent sides of the body portion of the calk to assist in holdin the calk from twisting or turning on the s oe while in use. As shown the groove in each heel is slightly inclined with respect to the end of the heel and is spaced an appreciable distance from said end. Each groove extends entirely across the heel and the vertical opening communicates with said groove. The calk snugly ts in the groove and is of the same length as the width of the heel part of the shoe. Manifestly I have devised ahorseshoe call; which can be used in connection with the ordinary well-known form of shoe, the calk being .simple in construction and capable of being quickly and easily associated with or removed from the shoe when desired.

Vhat is claimed is A horseshoe having each heel part provided With a transverse groove on its ground face, said groove being slightly inclined with respect to the end of the heel and extending from edge to edge of the heel and being l0- cated an appreciable distance from the end of the heel, each heel part having a vertical opening communicating with the groove, and a calk having a stud engaging the opening and a body part of rectangular form and of the saine Width as the heel part and iitting 15 snugly in the groove With its side Walls engaging the side Walls of the `grove.

ln testimony whereof I aiiiX my signature.

SETH BORTREE.
